Security researchers announced the Ryzen vulnerability and only notified AMD 24 hours in advance.

Security researchers announced the Ryzen vulnerability and only notified AMD 24 hours in advance. Due to the emergence of Meltdown and Spectre, there is a shortage of potential security vulnerabilities for modern high-performance processors, especially those that handle the core and key components of the company's business and international infrastructure. Today, CTS-Labs, an Israeli security company, published a white paper stating that there are po

Css pre-processor, post processor, and css Processor

Css pre-processor, post processor, and css Processor Because I was just getting started with the front-end, I read the knowledge that a great master wrote yesterday, and then I began to search one by one, the following are my search results for css preprocessors and post-processors. First, I would like to share with you the knowledge in this area. On the other ha

Clarify Processor, Processor Sockets, Processor cores, Logical processors, hyperthreading these concepts

If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core

Java uses the annotation processor to generate code-Part 2: annotation Processor

Java uses the annotation processor to generate code-Part 2: annotation Processor This article is part 2 of my "using annotation processors to generate code for Java" series. In the first part (please read here), we will introduce Java annotations and several common methods. Now, in the second section, we will introduce annotation processors. This includes how to create annotation processors and how to r

The clock synchronizes internal CPU operations and other system components. TheControl Unit(Cu) coordinates the sequencing of steps involved in executing machine instructions. The Control Unit coordinates the steps in the machine instructions. The

The third stage of Self-writing processor-the blueprint for the openmips processor for Teaching

I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday. This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the ope

One hour to figure it out. Annotation Processor (Annotation Processor Tool)

The annotations in Java are a magical thing that you don't know yet. You can see the custom annotations (Annotation) for the next hour. Now a lot of Android libraries are implemented using annotations, such as butterknife, we do not want to learn, we learn the note processor, we try to write a simple similar to the butterknife of things to bind the control.What is an annotation processor? The annotation

E3 and i5, which one? i5 processor and E3 Processor Difference comparison Introduction

Small series found that recently a lot of enthusiastic netizens in the network asked a more representative question: about E3 and i5 processor which is good? E3 and i5 which is good i5 compared with E3 processor In the current high-end mainstream installed, the most choice is i5 and E3 processor, which i5 and e3-1230 price difference is not much, bu

Communication between the core of the baseband processor and the application processor

The current mobile phone architecture uses a variety of communication methods between processors. Currently, the popular interfaces of split AP and CP include SPI, I2C, UART, USB, and dual-port interconnection, shared Memory is used in the SOC mode. The control commands are transmitted between the baseband processor and the AP processor in the message format to complete functions such as calls, short messag

Architecture, instruction set, Processor IP core, and processor of arm series Processors

0. Processor Simple classification: The CPU is also called the MPU-microprocessor or Central Processing Unit. It is the core of computer control and control. It can also be used as the core of computing. Of course, it can be used as another computing core. MCU, also called SoC-microcontroller, is also called an on-chip system. Its functions cover CPU and other functions. At the same time, the chip is integrated into the control cores such as bus
